Cable Wires

I don't really understand why guys are so into techy stuffs. My husband loves wiring and electronics. Though he is not a graduate of electronics he just love to see wirings on his things. And if our bus needs electronic repair he will try to repair it. There are a lot of names in wiring which I really can't understand. Like this Cat5E. If you'll ask me on what it is I won't be able to answer you because I really don't know what it is. I only found out that it is a kind of cables. Well if you'll ask hubby about it he will be able to answer you. Me? Don't bother. hahahahah!
